Kitchen renovation and the gas line: plan it before the carpenter starts

A modular kitchen is planned around the carcass, the shutters and the granite. The gas line usually comes last, when the carpenter asks, “pipe kahan se aayega?” By then the cabinets are built, the hob cutout is made, and the only route left for the pipe is the wrong one. This article is about planning the gas side of a kitchen renovation first, so the new kitchen is safe, meets your gas company’s rules, and stays easy to service.

Decide the cooking position before anything is built

Everything else follows from where the hob or stove will sit. Fix that first, with these in mind:

• Not under a window that opens over the flame, where wind can blow it out or curtains can reach it.
• Not right beside the sink. Water splashing onto the burners and the gas connection causes corrosion and ignition trouble.
• Not beside the fridge. Heat from the burners and the fridge’s own warm back are a poor combination.
• Room for a chimney above, with a short, straight route for its duct to an outside wall or shaft.

Plan the gas point and the valve

Once the cooking position is fixed, decide where the gas arrives:

• The appliance valve must be easy to reach, without emptying a cabinet or bending under the counter. In an emergency, the person closing it may be panicking. A valve inside a cabinet works only if that cabinet has a door that opens without a tool and nothing stored in front of the valve.
• The hose from the valve to the hob or stove should be short and visible, not running through drawers, behind an oven, or across a hot surface.
• Keep the gas point away from electrical sockets, especially the socket for a chimney, a hob’s ignition or a microwave below.

Our article on the routing rules an installer must follow explains the distances and the materials in more detail.

Piped gas: talk to the gas company first

If your home has PNG, the pipe from the meter into the kitchen is part of a regulated installation. Moving the gas point, extending the pipe or changing its route is done by your gas company or by someone they approve, and it ends with a pressure test. Apply early: the visit may take time to arrange, and the carpenter will need to work around the final position.

Never let a carpenter, a plumber or an electrician move, cut or bend a gas pipe, even “just a little”. A pipe that looks fine can have a strained joint that leaks weeks later. Gas work is done by a gas technician and always ends with a leak test.

LPG kitchens: cylinder placement

With LPG, decide where the cylinder lives before the cabinets are built. The safest place is upright at floor level in a well-ventilated spot that is easy to reach, with the regulator in sight. If the cylinder must go inside a cabinet, that cabinet needs permanent ventilation at the bottom (LPG is heavier than air and pools low) and nothing else stored in it. Some homes move the cylinder outside the kitchen with a fixed copper line to the stove; that needs a proper installation and a pressure test, not a long rubber hose through the wall.

The cabinet under the hob

• Ventilation. Openings at the bottom of the cabinet or in its back, so that any gas cannot collect.
• Access. A technician will need to reach the hob’s gas connection and ignition from below. A drawer unit directly under the hob makes that much harder; a shuttered cabinet is easier.
• No storage of chemicals, paper or plastic bags right under the hob.
• The right cutout. The carpenter should make the cutout from the hob’s own manual, not from a standard size. If you are reusing an old hob or buying the hob later, see when a hob does not fit the cutout.

Mark the pipe before work starts

Before drilling begins, mark on the wall where the gas pipe runs, and tell everyone on site. A drill bit through a gas pipe inside a wall is a serious accident. Where the pipe passes behind cabinets, the cabinet backs should leave it visible or easy to reach, never boxed in solid.

Sequence that works

1. Fix the cooking position, the chimney position and the duct route.
2. Choose the hob or stove and get its manual.
3. Plan the gas point and the valve position; apply to the gas company if it is PNG.
4. Electricals: sockets for the chimney, the hob ignition and other appliances, away from the gas point.
5. Carpentry and countertop, with the cutout from the manual.
6. Gas connection and leak test, then the hob or stove is connected and tested.
7. Chimney installed and its duct sealed at the wall.

Questions people ask

Modular kitchen banwa rahe hain, gas pipe kab shift karwayein?

Before the carcass is built, once the hob position is final. For PNG, apply to your gas company early. For LPG, have the copper line or the cylinder position done by a gas technician before the countertop goes in.

Can the gas pipe go inside the wall?

Rules differ by gas type and gas company, and many installations require the pipe to stay exposed or accessible. Ask your gas company before planning any concealed route.

Do I need a leak test after renovation?

Yes. Even if the gas pipe was not moved, the hob or stove has been disconnected and reconnected. Every joint should be tested before the first meal.

If you are renovating and want the gas side planned, connected and tested, book a gas pipeline visit before the carpenter starts. A visiting charge applies, and you are told the cost of any part before it is fitted.
